[jira] [Commented] (OLINGO-512) Problem when updating a navigation link with cardinality n > 1

["Thierry Templier (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OLINGO-512?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14237916#comment-14237916 ] 

Thierry Templier commented on OLINGO-512:
-----------------------------------------

After investigating more the issue, I found out that using the method appendEntitySetSegment of the URIBuilder fixes my issue:

URI categoryRef = client.newURIBuilder(serviceRoot)
    .appendEntitySetSegment("Categories").appendKeySegment(2)
    .build();

> I try to update a navigation link of an entity with cardinality n>1 as described below:
> String serviceRoot = (...);
> URI productUri = client.newURIBuilder(serviceRoot)
>     .appendEntitySetSegment("Products")
>     .appendKeySegment(1)
>     .build();
> ODataEntity productUpdates = client.getObjectFactory().newEntity(
>     new FullQualifiedName("ODataDemo", "Product"));
> URI categoryRef = client.newURIBuilder(serviceRoot)
>     .appendEntitySetSegment("Categories")
>     .appendKeySegment(2)
>     .build();
> ODataLink category = client.getObjectFactory()
>     .newEntityNavigationLink("Categories", categoryRef);
> productUpdates.getNavigationLinks().add(category);
> ODataEntityUpdateRequest<ODataEntity> req = client
>     .getCUDRequestFactory().getEntityUpdateRequest(productUri,
>                       UpdateType.PATCH, productUpdates);
> ODataEntityUpdateResponse<ODataEntity> res = req.execute();

> }
> and the simplified content of the response:
> HTTP/1.1 400 Bad Request
> {"error":{"code":"","message":"An error occurred while processing this request.","innererror":{"message":"The resource set reference navigation property 'Categories' has a property annotation 'odata.bind' with a string value.
